int HYPERVISOR_platform_op(struct xen_platform_op *platform_op) to allow
compiler type checking and match the x86 version.

Also, the implementation of the helper differ from x86. On x86, the
helper takes care of setting the interface_version while here you
request the caller to do it.

It's better if we have similar requirement across the architecture as
this helpers may be called from common code.
